Abstract: An evaporator has an outer peripheral side held by a holding portion. The evaporator includes a body portion and a packing located on a part of the body portion that faces to the holding portion. The packing includes an inner elastic layer and an outer elastic layer. The inner elastic layer has a water absorbability smaller than that of the outer elastic layer and is made of a closed cell foam member. The outer elastic layer is made of an open cell foam member. The holding portion includes a first rib preventing an air from flowing along the outer peripheral side of the body portion, and a second rib preventing a displacement of the body portion. A thickness of the outer elastic layer in a condition where the outer elastic layer is not held by the holding portion is larger than a protrusion length of the first rib.
